Newman signed a minor-league contract with the Diamondbacks on March 28.
Newman opted out of his minor-league deal with Arizona on March 27 after missing the Opening Day roster, but he re-signed with the organization a day later. The 30-year-old could receive a look in the big leagues since Geraldo Perdomo (knee) is soon heading to the injured list and top prospect Jordan Lawlar is out multiple months after thumb surgery.
